321 Stainless Steel

Type 321 stainless steel is similar to Type 304 stainless steel, however, it contains a Titanium addition of at least five times the carbon content. This addition is made to reduce or eliminate chromium carbide precipitation - resulting from welding or exposure to high temperatures. Maximum stabilization is accomplished by annealing between 1750° and 1850° F. Type 321 has extensive use in aircraft parts, such as exhaust systems where operating temperatures are higher than 800° F. and where corrosive conditions are not too severe; also because of its resistance to scaling and vibration fatigue.

Typical applications: Aircraft Exhaust Stacks and Manifolds, Chemical Processing Equipment, Welded Equipment, Jet Engine Parts, etc.
